Abstract: A method for constructing a three-dimensional laminated shape includes selecting a first lamination strip from a plurality of lamination strips with different widths assembled on a spool. The first lamination strip is stacked on a stacking device and is cut at a first lamination length. A second lamination strip is selected from the spool. The second lamination strip is stacked and cut at a second lamination length different than the first lamination length. The process is repeated to construct a three-dimensional laminated shape of an electrodynamic device. In another embodiment, a computer readable storage medium includes executable instructions to collect design information characterizing a three-dimensional laminated shape and compute lamination parameters based on the design information.

Abstract: Embodiments of various rotor assemblies can include an arrangement of magnetically permeable structures including confronting surfaces oriented at an angle to the centerline, and different subsets of non-confronting surfaces. Different magnets can be disposed adjacent to the different subsets of non-confronting subsets. For example, one type of magnet lies is a flux path or a flux path portion passing through one subset of non-confronting surfaces, and another type of magnet is external to the flux path adjacent to another subset of non-confronting surfaces and is configured to boost the flux associated with the flux path (or a portion thereof). In some embodiments, the magnetic region can include a portion of the internal permanent magnet. One example of a rotor assembly is an outer rotor assembly.
